Ultra low range turbidity measurement.
Filtertrak Laser Nephelometer offers the best resolution in the market. Detects changes in turbidity as low as 0.0005 NTU. Complies with USEPA approved Hach Method 10133 for regulatory reporting and compliance monitoring. Compatible with Hach Multi-Sensor, Multi-Parameter Digital Controllers, sensor can be used with Hach’s new SC200 or SC1000 Digital Controllers. Includes Manual and Stablcal Turbidity Standards.
The FT660 is passing the torch to the TU5400 sc. The last day to order the FT660 is July 27, 2018. See the recommended products section of this page or visit HachTU5.com to learn more.
